To all whom it may concern:

Be it known that EDWARD Lox, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, has invented a certain new and useful Demountable Motor, of which the following is a specification.

My invention relates to motors, more particularly to demountable toy electric motors, and the objects of my invention. are: First, to provide a motor of this class which may be readily, easily and simply assembled and disassembled so that a child may easily assemble and disassemble the same; second, to provide a motor of this class in which various parts may be readily interchanged; third, to provide a motor of this class for elementary instruction purposes and which will easily and readily convey the fundamental principles of mechanics and electricity; fourth, to provide a motor of this class in which the various parts are very simple of construction so that they may be manufactured very economically and easily replaced or repaired; fifth, to provide a novel and attractive means for displaying and offering for sale the motor in disassembled form; sixth, to provide a novelly constructed motor of this class, and seventh, to pro-- vide a motor of this class which is very durable and which will not readily deteriorate or get out of order.

ith these and other objects in view as will appear hereinafter my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a plan View of my motor with a portion of the frame broken away to fa cilitate the illustration; Fig. 2 is a side elevational view thereof; Fig. 3 is an end elevational view thereof; and Fig. 4 is a plan view of a container with the cover partially removed and shown fragmentarily and showing the various parts of the motor in disassembled form arranged therein.

- Like characters of reference refer to similar parts and portions throughout the several views of the drawings.

The base 1, upright members 2, screws 3,

plate 4, bolts 5, electromagnets 6, screws 7, shaft 8, armature 9, cam-shaped circuit maker 10, brush 11, washer 12, support 13,

upper surface of the base 1, which is preferably made of wood, by the screws 3. Said uprlght members are tied together and braced at their upper ends by the plate 4 i which is secured to the said upright membersby the bolts 5. Electromagnets 6 are secured to the inside face of each of said upright members 2 by the screws 7 and are electrically connected. with each other by the conductor 6 and grounded to the frame by the conductor 6*. A shaft 8 is revolubly mounted in the upright member 2 of the frame and is provided at the middle portion thereof with a slightly raised knurled portion 8 adapted to receive thereon the arma ture 9 which rotates with said shaft between the cores of the two electromagnets. Said armature 9 is preferably made of insulating material and is provided with a plurality of magnetic material cores 9 insulated from each other adapted to be moved by and he acted upon by said electromagnets. Also mounted upon the shaft 8 is a circuit maker, 10- preferably on the outside face of one of the upright members 2,.which circuit maker also serves as a collar against said upright member. Said circuit maker is preferably made polygonal in cross section, corners or raised edges thereof varying directly with the number of cores in the armature. Said circuit maker is provided with a longitudinal slot .10 to permit said circuit maker to be easily one of said electromagnets, are adapted to be connected to a source of electrical energy not shown on the drawings. A sheave 17 is also mounted on the shaft 8 at the opposite end from the circuit maker 10 adapted to also serve as a collar against the other of the upright members to prevent end play of said shaft and position said armature with relation to the cores of the electromagnets. The hub 17 of said sheave is longitudinally slotted at 17 which provides a semi-rigid mounting of said sheave when the free portions of said hub are slightly forced together, similar to the circuit maker 10 as previously described.

It will be here noted that when electrical energy is passed through the conductor 16 and the brush 11 is in contact with the circuit maker 10, the core in the armature will be attracted by the electromagnets, rotating the armature in one direction depending upon the relative position ofthe circuit maker with respect to the cores in the armature. If the position of the circuit maker is changed sufliciently and moved about the shaft in the direction of the arrow, as shown in Fig. 3 of the drawings, the armature will revolve in the opposite direction due to the closer proximity of the lower cores of the armature to the electromagnets than the upper cores of the same.

Though I have shown and described a particular construction, combination and arrangement of parts and portions I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious from the drawings and the description that I have provided a motor that may be easily assembled and disassembled; that various parts may be readily interchanged; that the various parts are very simple of construction and may be economically manufactured; that I have provided a motor which will readily convey to a student-or others the fundamental principles of mechanics and electricity, and that I have provided novel means for displaying and offering for sale the motor in disassembled form.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
